Re: The monsters wakes up ! Katla Hekla Iceland Dead Zone and rift as uniform system ! A lot of others worldwide !

Every cam im looking at shows volcanos starting to come to life ,this could be the start of a mini ice age with the sun blocked out for many years ,all thats missing at the moment is a super volcano and if one of those goes

Man, do not worry so much! You are so close to Iceland so that you do not even have time to get scared(hope I calmed you no worse than Carl)

Just waiting for them to say loch ness in scotland or Scafell in the Lake District supervolcanos have come back too life then all will be good

No one really knows, with any absolute certainty, just how old the Universe, or this planet are. With plate tectonics, the land is constantly changing. Old land is being subducted and melted back into the core, land that was on top of the part that was subducted sinks...sometimes into the ocean...and then one day "Whoosh!" out it comes on the other side of the planet. How many traces of civilizations have come and gone this way, only to become new land on the other side of the world?

[link to www.wired.com] ...Costa RicaThe RSN in Costa Rica released a report about changes at some of the most active volcanoes in the country after the M7.6 earthquake that struck the country last month. Although the direct connection between large earthquakes and eruptions is not settled, the RSN has noted that some Costa Rican volcanoes have experience heightened activity after large earthquakes (> M6.5), so they felt it was important to check to see what changes the active volcanoes of Costa Rica may have experienced since the earthquake. Overall, it looks like Turrialba, Poas and Rincon de la Vieja saw an increase in fumarolic activity (degassing) and Poas may have even had a small phreatic eruption in the days after the earthquake. Arenal and Irazu seem to not had any changes since the earthquake – however, one should take this cautiously as only a month has passed since the earthquake occurred...

... The analysis of the M5.6 main shock revealed a normal-faulting source mechanism (downwards movement), which indicates it to be linked to the extension of the Eyjafjaroarall graben system and not directly to the Husavik Flatey Fault, which shows horizontal strike-slip movements. It is neither possible to estimate how long this activity will be ongoing, nor can further earthquakes of M>4 be excluded.

This seismic sequence is located close to the western end of the Husavik Flatey Fault and it can not be ruled out that it will effect the stress field of this fault. A rifting episode during the Krafla fires 1975-1984 caused a stress decrease on the Husavik Flatey Fault and stress is accumulating on the fault system again since then. Deformation measurements (GPS) reveal that the Husavik Flatey Fault has accumulated enough stress for an earthquake around M6.8 (Metzger o.fl., 2011)

The strongest earthquakes known on the fault were around M7, e.g. 1755 and 1872 in the Skjalfandi bay.

A NASA satellite image of Heard Island on October 13th shows Heard covered in a white ice sheet. The summit crater was unusually dark, with a possible lava flow in its crater. Strong heat signatures were detected in its crater.

[link to hisz.rsoe.hu] ...The Australian Government's official Heard and McDonald Island website, which has a nifty .aq domain, reports eruptions on McDonald Island. In 1992. Heard Island's remote location means any eruptions are unlikely to bother anyone, as the region has no history of colossal, world-shaking, events. Penguins and expeditions that plan to visit the islands are, however, in jeopardy. Two of the latter are scheduled for the near future. In 2013 a solo adventurer plans to sail to the islands and then kayak ashore.

[link to www.wired.com] mattmabus I wonder if the verdict in Italy had any impact on the decision by Icelandic seismologists to declare an "Uncertainty Level" for the swarm that is ongoing in the TFZ of northern Iceland.

Re: The monsters wakes up ! Katla Hekla Iceland Dead Zone and rift as uniform system ! A lot of others worldwide !

Probably not the topic, but very interesting [link to hisz.rsoe.hu] A sharp tremor was recorded by USGS monitors just after 9 p.m. Wednesday at the site of the giant Louisiana sinkhole in Assumption Parish. The giant sinkhole appeared in August near the Bayou Corne and Grand Bayou areas. The Assumption Parish Police Jury says the tremor was large enough that the body wave phases could easily be identified.

[link to www.jonfr.com] Uncertainty level is declared in north Iceland due to risk of large earthquake from TFZPosted on October 24, 2012 by J&#243;n Fr&#237;mann Uncertainty level has been declared in north Iceland due to risk of large earthquake taking place in TFZ.

[link to icelandreview.com] The Civil Protection Department’s council of scientists met yesterday and concluded that in the region currently subject to seismic activity, strong earthquakes occur two to three times per century. Strong earthquakes are also known to accompany series of earthquakes. The one currently ongoing is the most powerful in 20 years in the respective region, the council pointed out. It should also be kept in mind that a large earthquake on the Husavik-Flatey fault might trigger another large earthquake either on the same fault or the Grimsey fault, which lies to the northwest of Kopasker

Multibeam sonar image of Havre seamount, with the new cone formed during the July 2012 eruption marked. Image: NIWA, GNS Science: [link to www.wired.com] ...A group of New Zealand geologists abroad a research vessel used multibeam sonar to map the seamount and they found evidence of a new volcanic cone (see right) built on the side of the large submarine caldera that makes up most of the volcano. This cone is no small feature – the initial mapping suggests it is 240 meters tall, reaching within 1,100 meters of the surface.The pumice from Havre is still drifting in the seas near the Kermadec and will likely do so for years (or until they make landfall somewhere). However, it is great to see that our sleuthing through remote sensing has now been confirmed by direct observation of the seamount and the product of the eruption.
